Finite element methods for Yield Line Analysis

AI Thread Summary
To accurately estimate yield lines in reinforced concrete (RC) structures, understanding the loading transferred from slabs to beams is crucial. The discussion emphasizes the need for clarity on the formation of yield lines and their correct application to beams, particularly when using finite element methods (FEM). While the individual has foundational knowledge from various texts, the process of refining pseudo yield line patterns through methods like Virtual Work and the Equilibrium Method remains unclear. The conversation seeks insights on implementing these concepts effectively within FEM frameworks. Overall, guidance on yield line analysis and its integration with FEM is requested for better comprehension.

Hi All,

I'd like to what kind of steps need to be taken to accurately estimate the yield lines of RC structures. My intention is, to know what type of loading is acting on beams transferred from slabs. I know how to formulate thin/thick plates and shells. The results converges with commercial packages but how is the way obtain the yielding line formation and how to correctly transfer it to beams?

It doesn't mean that I'm completely new to the yield line analysis, I've read the Theories and Applications of Plate Analysis by Rudolph Szilard and many nomenclatures e.g.
"GENERAL COMPUTER PROGRAM FOR THE YIELD-LINE SOLUTION OF EDGE SUPPORTED SLABS"
"A computerised method for rigid-plastic yield-line analysis of slabs"
"NUMERICAL YIELD LINE ANALYSIS" by D. BAUER and R. G. REDWOOD

Many of them starts with pseudo yield line pattern where I'm completely confounded how they found it and proceed with refinement and optimization of it, either by Vurtual Work and Equilibrium Method to find the correct Yield Line pattern. Although I've introductory info, this still remains unclear and vague for me. Does anybody can shed some light on that, especially how can be implemented with FEM.

Your comments will be appreciated!

Best Regards,

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
